摘要： The present invention relates to an apparatus and a system for curing a liner extending in a pipeline or at least in part in a branch pipeline, where the liner includes a substance such as a synthetic resin suitable for being curable by exposure to electromagnetic radiation. The apparatus comprises an actuator constituting an electric, hydraulic or pneumatic actuator, and including an actuator member and an actuator axis substantially parallel to the axis of the pipeline when said apparatus is in its intended operational position in said main pipeline. The apparatus also comprises a light head having a light source for emitting electromagnetic radiation for curing said substance, and connected to the actuator member, where the actuator and actuator member are configured for applying a force to the light head in a direction substantially parallel to the actuator axis for displacement of the light head, such that the substance being cured as the light head moves through the pipeline and exposing the substance to electromagnetic radiation.

摘要： An assembly for relining a junction between a branch pipeline and a main pipeline comprises a seal installation device capable of moving within the main pipeline to the junction. The seal installation device includes a curable seal for being placed and pressed onto the junction and optionally for extending into the branch pipeline. The assembly further comprises a light curing device for being introduced into the seal installation device within the main pipeline and the branch pipeline for curing the seal.

摘要： A system for curing a pipeline liner that includes a resin curable by exposure to radiation includes first and second liner curing apparatuses, each of which includes a housing defining opposite first and second ends, and outer and inner walls defining a passage between the first and second ends; a plurality of LED's on the outer wall and operable to irradiate the radiation; and a plurality of heat dissipating elements on the inner wall. The LED's are connected in thermally-conductive relationship to the heat dissipating elements, whereby heat is dissipated from the heat dissipating elements to cool the LED's when a stream of cooling fluid passes through the passage. In use, the apparatuses, joined end-to-end, are moved within the liner while irradiating radiation from the LED's onto the liner, and the velocity of the apparatuses moving through the liner is adjusted to cause a complete curing of the resin.

摘要： The invention relates to a method of relining a sewer pipe having an area in need of repair. The sewer pipe is accessed via an access bore having an upper end and a lower end, and an access point at the upper end, and connected to the sewer pipe at a bore-pipe junction at the lower end. The method comprises providing a liner for inserting inside the sewer pipe such that the sewer pipe is relined. The method further comprises providing a tube for inserting said liner into said sewer pipe, and everting the liner such that the liner is turned inside out and said inside surface constitutes a temporary outside surface, placing the everted liner inside the tube such that the tube includes the liner and constitutes a tube-liner assembly having a free end, and moving the tube-liner assembly into the access bore with the free end such that the free end of the tube-liner assembly extends into said sewer pipe, inverting the tube-liner assembly when the free end is at bore-pipe junction such that the liner being placed with the outside surface facing the sewer pipe and covering the area in need of repair.
